The attaching device holds and anchors a portion of the engaging loop and the user&#39;s original hair, and the extending hair bundle, the bundle tip, and the engaging loop are fixed to one another permanently so as to form a hair extension assembly. When the attaching device is detached from the strands of the user&#39;s original hair and the engaging loop, the assembly is freed and reusable.

BACKGROUND OF THE INVENTION

The present invention relates to a multi-point hair extension.

Current hair extension techniques involve braiding or weaving hairextension pieces into the user's original hair using hot glue. Thisprocess can damage the user's existing hair due to the heat of the glueand from excessive twisting of the existing hair during the process ofbraiding or weaving.

Furthermore, removing the applied hair extension from the client's hairrequires a process involving heating the glue that attaches theextension to the client's original hair. This process leaves glueresidue in the client's hair, the removal of which requires washing theclient's hair in an oil substance. This time consuming process is anecessary step for the final result of fuller and beautiful hair.

Accordingly, the need for a multi-point hair extension of the presentinvention has existed for a long time, considering the excessive cost,time, and damage to the user's hair.

DETAILED DESCRIPTION EMBODIMENTS OF THE INVENTION

The invention relates to prepared single or multi-point extension onto auser's existing hair with minimum application time.

Hair extension and enhancement systems for women and men are widelyused, spreading worldwide to meet current society's standard of enhancedpersonal image. Hair extension techniques were developed by and forAfrican American women who desired longer and fuller hair. Weavingtechniques were developed initially in a manual braiding form and then amachine made process in which either synthetic or natural weft hair wassewn into a pre-established track line on the user's scalp.

Whether hair extension and enhancement is the result of trends in modernfashion or personal needs, the demand for beautiful hair has increasedto an explosive level, creating a multi-billion dollar industry, andthus creating many different hair extension concepts that add to thelength or fullness of the user's natural hair. For hair extensions, manmade synthetic hair can be used. However, real human hair is moredesirable because of its luxurious look and feel when touched.

Multi hair extension fastening methods are being developed to attachadditional hair to the user's natural hair so as to either extend lengthor increase hair volume. These methods include fusing the hair extensionand natural hair with hot glue, bonding a band of strip hair to theuser's scalp, weaving weft hair or a cylinder anchoring bundles of haironto a user's existing hair. While clipping a piece of hair onto theuser's existing natural hair and wig applications are commonly used, apermanent attachment method is preferred as it gives the user a securefeeling by eliminating the worry of the hair coming off.

Women's hair loss patterns differ from men. Women typically experiencehair loss through thinning on the top of the scalp whereas menexperience hair loss through baldness. Therefore, women are moreinclined to utilize hair extension methods to lengthen or increase thefullness of natural hair rather than using topical hairpieceapplications or wigs. There are some exceptions to this, notably whenwomen experience total hair loss from Alopecia or chemotherapytreatment.

Hair extension requires minimum existing hair to which the new hair isaffixed either for increasing length or fullness. One importantadvantage for women using hair extension methods rather than a hairpieceor wig is that hair extensions are attached as strands only as needed tosupplement the user's natural hair, while hairpieces and wigs force theuser to wear a piece that either partially or entirely covers the user'shead. At the same time, due to the complexity of application and thustime involved, there are drawbacks to the individual hair extensionmethods currently used. Furthermore, the techniques involved in allcurrent methods require the skill of highly trained beauticians.

From various methods of application, the easiest, fastest, yet leastdamaging to the user's existing hair has been pursued to meet today'sdemand from women and men alike.

Individual hair extension methods require hours of time for itsapplication as each individual bundle of hair is to be attached to thecorresponding amount of the user's existing hair. It could take anywherefrom 4 to 15 hours or even longer depending on the amount of fullnessneeded by each individual. The invention of prepared single or multipoint hair extensions is designed to save time by using two separateindividual extension pieces instead of a single extension. The inventioncuts down the time needed to complete an application of an individualextension by more than 70 percent. Furthermore, single or multi pointhair extension minimizes damage to the user's existing hair byminimizing the need to physically manipulate the user's base hair.Current individual extension techniques require 100 strands of theuser's existing hair for each 100 strands of individual extension hair,whereas the new invention applies 200 strands onto 100 strands ofexisting hair.

This technique not only saves time, but also uses less of a user'sexisting hair. The new invention also confers benefits by minimizingdamage to the user's existing hair.

The invention further relates to the natural flow of single or multipoint hair extension by minimizing the space between individualextensions and the user's hair when the extension is attached to theuser's hair. The invention allows for maximum results with minimumapplication.

This invention further allows the reuse of a single or multi point hairextension, as the design attaches the portion of a single or multi pointhair extension to a micro cylinder through the use of a non-slip, wireor plastic, fishing line like thread.

Hair extension is a technique by which a piece of prepared hair isattached to the user's existing hair. The process may occur either pieceby piece, by weave, or by a strip of hair glued onto the scalp. Themethods of attaching a piece of hair to the user's existing hair arerather complicated, thus only well trained technicians are allowed toattempt the job and it can take anywhere from a couple hours to wellover ten hours. Both hair technicians and clients have to invest largeamounts of time, which translates into large dollar cost. Because themethods take many years to master, and because many tools are required,hair extensions for an individual user can cost anywhere from $500 to$8,000 depending on the length, quality and technique used. Even withthe high cost of hair extension, there are still adverse effects ofcurrent hair extension methods, primarily from damaging the user'sexisting hair. The damage is primarily due to required application ofheated glue to attach the extension and the user's natural hair, andalso the excessive weaving/braiding of the user's natural hair, or dueto the cylinder tube used to anchor the prepared hair onto thecorresponding amount of the user's existing hair. Often, twisted orbraided hair applications make the user's hair bumpy to the touchwherever extension is applied. Moreover, available methods of hot glueor weaving extensions are harmful to the user's existing hair, eitherdue to the required application of heat or, for the weaving method, dueto traction alopecia which results from excessive tying and pulling ofthe user's existing hair that is required to attach it to the hairextension.

There are other adverse effects of existing hair extensions. The cost issignificant, averaging $800 to $5,000 per extension process. The resultis often bulky enough to feel the ridge along the scalp, which isrequired for heavy extensions. The bulky nature of the extension alsocontributes to excessive hair loss due to improper air circulation ofthe scalp and the bulky extension's excessively tight pull on the user'snatural hair.

Current available hair extension methods are:

Glue extension: The application requires dipping loose hair into acontainer of hot glue. The glued portion of hair is then applied to anexisting piece of the user's hair and the two are rubbed together, thusforming the attachment. This application is not only messy but can alsocreate danger to applicant's fingers as well as the client's scalpduring application and removal. Another hot glue hair extension methoduses prepared glue tip extensions. Heated pliers are used to melt theextension onto the user's existing hair. Strong chemical solvent is alsoused to remove the hair extension at the time of a readjustment or a newapplication. These hot glue extension techniques involve heat and thusrequire special training for safety purposes.

Hot glue extension processes require heat to apply the extension, andthen require cracking the hard extension tip to remove or renew theextension. Additionally, the use of chemical solvents is required toclean the glue or wax residue from the user's hair. Thus, the processcan damage the client's existing hair. The process also requirestremendous time consumption. Hot glue hair extension technique processestake three to fifteen hours to complete. Furthermore, the removal ofextended pieces from the scalp prior to a new application also requireabout the same amount of time. This not only subjects both the applicantand the user to mental and physical exhaustion due to the various steps,but the chemical involvement and time consumption increase the cost ofthe process. The use of strong chemical solvents and the burning of gluecan also create unpleasant odors which may cause headaches to both theapplicant as well as the user.

Weaving hair extension: Various weaving hair extension techniques havebeen very popular, especially among African American women. The weavingprocess requires pre-made machine or hand made weft hair. The processcreates a horizontal track line to anchor the pre-made weft hair onto anestablished track line. The weft hair is anchored by tightening it witha fishing line type of thread. The main reason that weaving extension ispopular is that it is possible to add a significant amount of new hairin a rather short amount of time as compared to other current hairextension application processes. The three significant drawbacks ofweaving hair extension are: 1) Pre-weft itself is unavoidably quitebulky due to how it is made; 2) Track line on the client's head requiresa process of twining of the client's existing hair, creating tractionAlopecia around the area where the track line is made. This isespecially true for those who have fine or thin hair; 3) Uncomfortablepain is inevitable in order to create the necessary track line, as aportion of hair needs to be twined for holding the weight of the bulkyweft; 4) The already weft must be attached by sewing it into the user'shair by means of bulky and heavy weaving thread which adds additionalthickness to the weft; this bulky nature interferes with achieving thetrue beauty of hair extension. It gives the hair an unnatural look andfeel.

Strip hair extension: Strip hair extension is another extensiontechnique, which allows an increase in hair volume or length to a user'sexisting hair. Usually, glue or tape glue is applied to a flat skinstrip where the hair is added, then applied directly to the scalp wherethe hair is separate. Because of adhesion, strip hair adheres to thescalp. This strip hair, however, can easily come off of the scalpbecause of the scalp's natural production of scalp oil; thus, strip hairextensions must be reapplied frequently. Furthermore, applying glue orglue-like tape directly to the scalp is harmful to skin and createsdiscomfort to the user.

Cylinder tube hair extension: Using a cylinder as a medium, a piece ofthe user's hair is pulled onto the cylinder. Then a pre-glue tip hair ispushed into the cylinder tube, then by pressing the cylinder withpliers, the new extension piece of hair is attached to the client'shair. In case applicant uses loose hair instead of prepared hair, loosehair pulled into the cylinder tube needs to be in cross-cross knotsusing a crochet hook by going through cylinder. This process can createsuncomfortable pulling of the client's own hair during the process.

However, cylinder tube hair extension application is much simpler, saferand cleaner than hot glue or weaving techniques due to the lack of heat,glue or chemical involvement either in its application or removal. Theprimary drawback of the current cylinder tube extension is that eachindividual extension requires a 3 mm tube to anchor the hair, resultingin hundreds of aluminum/copper cylinder tubes on the client's head, butUser's who have sensitive skin or fine hair can only handle a limitedamount of cylinder tubes, which limits the effectiveness of theextension. Current cylinder extension requires a great deal of time forits application. Furthermore, the process of removing cylinder tube hairrequires opening up the closed cylinder with pliers. This processoccasionally pulls the client's hair that gets trapped in the cylindertube out along with the attached hair especially if the cylinder iscramped too tight by applicant. Therefore, highly trained hairdressersare only capable of performing this process.

The leading hair extension techniques currently being used are as listedabove.

The invention is designed and focused with the concept of a simpleapplication that minimizes time and cost while maximizing the beauty ofthe hair extension. Also, the invention applies the added value of safeapplication, as a protruded U shape of treated thread is threadedthrough an ultra micro cylinder. The size of the cylinder is less than ahalf size of a regular cylinder tube. Furthermore, the attaching mediumis not a piece of hair but rather is a treated thread which minimizesthe size of the cylinder tube once it is pressed. Also, it holds newextension hair much stronger while minimizing the possibility that theextension will slip. Occasionally, two different new and existing hairscan slip out of the cylinder tube due to the rather bulky cylinderextension tube.

The invention will allow the user to realize a simplified process thatminimizes time, potential damage to existing hair, and more importantlycost.

The main purpose of having a treated thread/wire/or similar threadedloop to be used to attach to the top end of a single or multi point hairextension is to allow for the secure holding of the extension. Thisoccurs due to the thin treated thread being attached onto the cylinderrather than a piece of hair. And this allows for the single or multipoint hair extension system to be used for multiple applications duringthe life span of the hair, rather than constant reapplication. Thiscreates economic value for the user. This multiple use of a singleapplication can be quite significant as each individual piece of hairextension can cost at least $5.00 to $15.00 per piece depending on thequality of the hair, its length and its reusability. Furthermore,reusable single or multi point extensions minimize the environmentalimpact of the process, as most individual hair extension currently beingused are designed with a life span of a single usage or two to threeapplications.

Discarding used hair extensions is inevitable because the hair is overlyprocessed and thus its life span is only two to three months. Moreimportantly, the glue tipped hair extensions that use polyurethane orsimilar wax cannot be reused once the wax hair tip is flattened, whichnormally occurs after the tip undergoes one or two pressings. Theattachment medium of the new invention is treated thread, pliable wireor even a piece of durable non-skid plastic that can be used for itsanchoring purpose. The advantage the new attachment medium is that itcan last many years, beyond the actual life span of hair.

Features of the new single or multi point extensions are:

1. Flat: Unlike the round forms of current existing individualextensions, the single or multi point extension of the new invention hasa flatter form, thus allowing the extension to blend in better with theuser's existing hair. It also gives the hair a more natural look andfeel. The new invention closely resembles the look of natural hairgrowth.

2. More hair: The new invention, Single or Multi-Point Extension, allowstwice as much hair per extension piece while using less of the user'sown hair. This is an important factor as many extension wearersexperience thin hair which limits the amount of hair to be anchored.

3. Time savings: The new invention, Single or Multi-Point Extension, canbe completed with at least 80% less time investment than other existingindividual hair extension application processes. Instead of 5 to 15hours, the new invention allows the process to be completed within 1 to3 hours.

4. No mistakes in attachment: Other individual cylinder methods requirea hair tip that is perfectly round in order for the extension hair toslide into the measured cylinder size. If the prepared individual hairextension tip is not perfectly round it will not fit into the cylinder.Additionally, because individual hair tips occasionally becomedisfigured, hair is often not able to be used and thus has to bereplaced. The same thing can happen after one or two uses: the glue tipof an individual hair extension becomes disfigured and will not fit intoa standard cylinder. The new invention of single or multi-point hairextensions prevents these mistakes as the treated thread tip is standardand much thinner than the glued hair tip, and thus can be reused withoutdisfiguring the shape.

5. Cost savings: The easy application and time saved by both thetechnician and client is directly related to cost savings. Also, theability to reuse the same hair extension system over a period of timehas less obvious cost-saving benefits. After a new hair extensionapplication, the hair stylist needs to cut over the length to adjust andshape the hair and this process can take anywhere from 30 to 90 minutes.However, this reusable extension allows the technician to apply theextension quickly as the cut and shaping of the hair is completed thefirst time.

6. No mess or fuss: Because of its simple yet effective application, thenew invention is a far from messy application, putting the user at easementally and physically during and after application.

7. Safety: Ease and simplicity of application means a safe application,which is a benefit to both the applicant and the user. Simpleapplication creates fewer problems if any, and even if problems arises,the simplicity of the application allows for simple solutions to theproblem.

8. Easy to learn: While current hair extension techniques involve manycomplicated tools, gadgets or devices, the new invention requires asimple pressing cylinder feeder. Because of the simple applicationprocess, there is no need to get hundreds of dollars worth of tools orundertake special training classes, which can run anywhere from $500 to$3,000 and last for many days.

9. Ability to combine application processes: The new invention can beused in connection with strip extensions to add highlights to the hairor more hair, if necessary.

10. Life expectancy: Compared with the commonly used individual hairextensions of today, the new invention, Single or Multi-Point Extension,has advantages which allow a much longer life expectancy, mainly becauseof its anchoring thread/wire loop design and the quality of itsenvironment-friendly natural hair process. The naturally processed humanhair requires many more steps in preparation while using approximately80% less chemicals, thus prolonging the hair life span much longer thanregular, chemically-processed hair.

Each piece of extension hair is evenly distributed in a flat skin likepolyurethane material, where the hair is imbedded in the form of naturalhair growth unlike bulky weft hair or round form glue hair extensions.Stiff U-formed thread is imbedded into each polyurethane tip extensionwhich is then inserted into each cylinder together with the customersown hair. The flat cylinder is than simply pressed tightly to hold boththe thread hook and the strand of the customer's hair.
